How's that?  RFC 2396 requires a scheme followed by a colon (for an 
absolute URI), or at least one character for a relative URI -

     rel_path      = rel_segment [ abs_path ]

     rel_segment   = 1*( unreserved | escaped |
                           ";" | "@" | "&" | "=" | "+" | "$" | "," )

So you have to have at least one character...

Cheers,
